Hmm.. I guess I'm talking about 593,138, but with the
addition of the
spark gap or tube switch driven by solid state
electronics.

Dr. Tesla said that 20kHz was an upper end of
operation, that higher
frequencies might be practicable.  Today we see coils
at much higher
frequencies. But his invention brought radiant energy
(aetheric) into
3-d space. This is what I am after. I don't believe
the coils built for
light shows today conform to Dr. Tesla's specification
(which he
stressed must be followed) and so are useful only for
lightning shows. I
want to tap the Radiant energy in the Natural medium.

I chose the frequency of 20 kHz as a starting point
because that's near
the frequency Stanley Meyer was working at. Can you
guess now what i'm
after? ;-)

Dr Peter Lindemann's book, "Free energy secrets of
Cold Electricity"
draws close parallels between the thestatika machine,
the EV Gray motor,
and Tesla's coils. Since it's probably easier to wind
a coil than to
build a van degraaf generator and leyden jars and all
the kit, or to
copy Edwin Gray's converter tube, I am exploring this
route to tap the
aether. Ideally my coil will sit in the corner of a
room, completely
quietly filling its collector plate with a positive
electrical charge
and providing at least some electricity for my home.
It is in a sense
the antithesis of most coils built by people on this
list. If anyone has
tried this already, I would love to hear from him and
learn from his
experience.

I hope no one is offended by my definition of Tesla
coil, but it doesn't
include anything not built to his spec, as closely as
is practicable.
His machines were pure non-oscillating DC impulse
driven. He spoke of
"tens of thousands of horsepower" and of a return of
1000 times the
input energy.

I seek to build a coil that will not even emit a
spark, which Tesla said
was wasted power.

Radiant power in the aetheric sense. A true Tesla coil
(according to
Tesla's patent cited above) does not emit Hertzian
radio waves, but
something of a different nature entirely. Radiant
energy which can be
picked up by copper plates and used to drive a load
and then the other
wire goes to ground. Brilliant, actually, and probably
more related to
Nathan Stubblefield's work than Marconi's.

593,138
I'll be powering it with wall current, run up to about
4kv and through a
bridge rectifier. Then I am considering using either a
vacuum triode (if
i can find one that will switch fast enough) or a
counterrotating spark
gap for the disruptor. the capacitor and disruptor are
described in the
patent text but the illustration doesn't show it.
Lindemann's book
includes it. (figure 21 in chapter 3)
